Function proptest::result::maybe_ok_weighted [−][src]
pub fn maybe_ok_weighted<T: Strategy, E: Strategy>(
probability_of_ok: impl Into<Probability>,
t: T,
e: E
) -> MaybeOk<T, E>
Create a strategy for Result
s where Ok
values are taken from t
and
Err
values are taken from e
.
probability_of_ok
is the probability (between 0.0 and 1.0, exclusive)
that Ok
is initially chosen.
Generated values shrink to Err
.
